This is something I didn't notice on my R8 for several weeks of ownership, I guess I'm more concerned with playing guitars than checking for flaws. It was after conditioning the fret board with Fret Doctor that I noticed the degree of overspray (at first I thought the Fret Doctor had smeared some finish from the neck). I thought maybe it was just my guitar but I just looked at a 2005 R8 on eBay with exactly the same overspray and it's just on the binding on the neck. Is this a common malady with the Gibson "Custom Shop"? Here's what it looks like on mine. Doesn't really bother me all that much cause it plays so sweet.
